Last year, I installed a Solarcan pinhole camera in my girlfriend’s back yard. See? Blog post to prove it.
But if you’re not feeling like reading an old blog post, I’ll give you the TL/DR.
A Solarcan is a specially-prepared camera. It’s a beer can that contains a sheet of photographic paper inside. A tiny pinhole allows the Solarcan to photograph the sun as it passes across the skies.
I installed the Solarcan on a power pole in my girlfriend’s backyard, with the pinpoint aimed towards the sun. That was last year.
Over the weekend, I retrieved the Solarcan, and last night, I cracked it open.
And this is what came out after ONE YEAR of soak.
Those curved lines you see are the sun’s path as it rises and sets. But this picture needs a serious enhancement. So let’s enhance. A level adjustment here, a cropping there, and …
Wow.
Now there’s a mystery to be solved. You can see the magnificent sun lines going across the skies here …
But what are those sun lines on the bottom of the picture?
I shall explain.
During heavy rainstorms, or after a long, snowy winter, my girlfriend’s backyard has a small drainage issue – the melting snow turns into a small lake. Eventually the lake disappears, but during that time, the Solarcan must have captured the reflection of the sun off the little lake. And THAT’s what caused the mirror-like sun trails on the lower half of the picture.
Now that’s impressive.
But yeah, this is the fun of passive solar pinhole photography. Sometimes you get great images like this … and when you do, it does show a nice result.
